Abstract

Taking into account the development of modern surgical stomatology, the problem of optimizing the closure of the wounds of the mucous membrane in the oral cavity remains relevant. In our opinion, it is important to study the morphological properties of the mucous membranes of the oral cavity and optimal tensions and tissue stresses in the area of suturing. It is known that the most susceptible to the action of mechanical factors area is the mucous membrane of the gums. However, taking into account the biomechanical parameters, the mucous membrane of the gum is practically not described. The aim of the study was to carry out a comparative analysis of mucous membranes of varying degrees of tension during fracture operations in the oral cavity. The material is taken to the bureau of forensic examination from corpses and both sexes and the period of mature age for histological studies of conditionally healthy mucous membrane of gum. The fence is carried out in the area of incisors, canines and first premolars from both halves of the upper and lower jaws with a standard dental instrument set were compared: a periodontological kit for curettage. The material is collected both in the area of papilla gum, and from its fixed part. Polarization microscopy is used to study the fibroarchitectonics of connective tissue formations. We used a contact strain gauge device to study the biomechanical parameters of the mucous membrane of the gums in normal and at different degrees of tensile of the mucous membranes. At various degrees of tension of the mucous membrane of the cavity of the mouth connective tissue plate loses the characteristic spatial orientation of the beams, the deep disruption of the entire fibrous frame occurs. Tissue stress recording was performed taking into account the tensile strength: weak (5%), average (7%) and strong (10%). Regardless of the degree of this pathology there is a decrease in the indicator we have chosen. Thus, with a weak degree of tension, the tissue pressure of the gum mucus decreases to 208.08 + 19.2 [6.07] Pa. At an average degree, the selected indicator is 149.43 + \ - 20.25 [6.4] Pa. A strong tension reduces the tissue tension of this area to 102.77 + 12.32 [3.9] Pa. One of the factors that provides high values of tissue gum voltage in the norm (350.4 · 9.69 Pa) is its fibrous components, which form a three-dimensional structure in the collagen beams of the 1st and 2nd order relative to the poorly developed elastic network. Different degrees of tensile of mucous membranes as a model of disorganization with the subsequent drop in tissue tension of the fibrous core were described. At the same time, the index of tissue voltage reduction is directly dependent on the tensile strength and is 208.08 + 19.2 Pa. The data presented indicate the disorganization of the fiber composition of the gums while tightening them. The expressiveness and nature of the changes depend on the degree of tension. Clinical manifestation of pathological processes in fibrous components of ascetic connective tissue is characterized by a decrease in tissue tension indices. Moreover, there is a direct relationship between the degree of tensile of the mucous membrane and the adequate reduction of the tense state of the soft core. Various degrees of tension of the mucous membrane can be considered as a kind of model of the fiber matrix with the dynamics of changes in the biomechanical parameters of tissues. The obtained data on the example of normal anatomy of the gums confirm the general pattern in the structures of the soft core - the quantitative ratio, the way of interaction of collagen and elastic fibers. Their spatial architectonics determine the deformative and strength properties of the connective tissue. For a detailed study of structural and biomechanical correlations we have selected mucous membranes with a different degree of tension. Our research has revealed structural changes in the fibrous gingival cortex against a background of different tensions with adequate tissue tension reduction.
